Specification of Letters Patent.

Patented Sept. 19, 1905.

Application filed January 2'7, 1905. Serial No. 242.966.

To all whom it may concern.-

Be it known that I, XAVIER KERN, a citizen of the United States, residing at Massillon, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Bending-Tools, of which the following is a specification.

This invention relates to improvements in that class of tools commonly employed for bending rails, pipes, or similar bodies, and aims to provide a device of this type of very simple construction and susceptible of use with a broader application than the devices which have heretofore been constructed.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings.

While the invention may be adapted to different forms and conditions by changes in the structure and minor details without departing from the spirit or essential features thereof, still the preferred embodiment thereof is shown in the accompanying drawings, in which Figure 1 is a perspective view of a device embodying the invention. Fig. 2 is a perspective view showing the invention as when in use for bending a pipe or similar body. Fig. 3 is avertical longitudinal sectionalview taken about central of the device.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters. I

In carrying out the invention a suitable frame 1 of approximately U form, such as is commonly employed, is used, and this frame carries the engaging members whereby the rails or other objects are shaped into the desired form. The ends of the frame 1 are formed with jaws 2, and the'sides of the frame are connected by a bar 3 near the rear end portions thereof. The bar 3 is connected with the rear end of the frame by transverse webs 4, being thereby reinforced, and between the bar 3 and the rear end of the frame is mountedan operating-lever 5. The outer end portions of the frame 1 adjacent the edges 2 are formed with vertical recessed portions 6, the inner terminals of which are transversely enlarged, and these portions 6 are adapted to receive a rail which may be placed in position upon the frame preparatory to being bent.

The means for bending the object to be operated upon consists of an actuating-bar 7, the body of which is threaded almost the entire length thereof, passing through horizontal openings in the bar 3 and the rear end of the frame 1. At its outer end the actuatingbar 7 is formed with a head 8, one side of which is recessed, as shown at 9, the recess being of substantially the same form as the recesses 6 in the end portions of the frame. The recess 9 is adapted to receive a rail, portions of which are also received in the recesses 6, and by imparting a longitudinal movement of the bar 7 through the medium of the lever 5 the head 8 may be forced inwardly or outwardly relative to the frame 1, so as to bend the rail outwardly or inwardly, as may be necessary. The jaws 2 are particularly designed to receive a pipe or tubular object, and the head 8 is provided upon the side thereof opposite that in which the recess 9 is formed with longitudinally-arranged pairs of lugs 10, corresponding pairs of said lugs being in transverse alinement and notched upon the rear sides thereof, as shown at 11.,

The lugs 10 admit of connection of the head 8 with the pipe or similar body resting in the jaws 2 by a chain, (indicated at 12 in Fig. 2,) said chain being provided at an end with a link or loop to receive the outer portion of the head 8, formed at the recess 9, the opposite end portion of the chain 12 being passed between the pairs of lugs 10 toadmit of engagement of certain links with said lugs. The

actuating-bar 7 may then be actuated so as to bend the pipe or other object, as deemed nee-- The mounting of the members 16 upon the.

sleeve 13 and bar 7 is such as to admit of free pivotal movement of the lever 5, and the head 15 is provided with pawls 17, mounted upon opposite sides thereof and normally adapted to engage the ratchet-wheel14 at their lower ends. Springs may be used to normally cause the pawls 17 to engage the ratchet-wheel 14, and a ring is mounted upon the head 15 and is designed to receive the upper end of one of the pawls 17 so as to hold the same out of engagement with the ratchet-wheel when the lever is being thrown into an ascertained direction.

Having thus described the invention, What is claimed as new is A bending-tool comprising a frame of approximately U form provided at its ends with jaws, the end portions of the frame adjacent the jaws aforesaid being recessed to receive a rail or the like, a bar connecting the sides of the frame and spaced from the rear end thereof, said bar and the rear end of the frame being provided with horizontal openings, a threaded actuating-bar mounted in the horizontal openings aforesaid and provided at its outer end with a head recessed upon one side to receive a rail, sets of spaced lugs projecting from the head of the actuating-bar upon the side opposite that provided with the recess above mentioned, a threaded sleeve mounted between the bar connecting the sides of the frame and the rear end of the frame, a ratchet-Wheel mounted upon said sleeve, a lever mounted upon the sleeve, and pawls carried by the lever for engagement with the ratchet-wheel to effect longitudinal movement of the actuating-bar.

In testimony whereof I affix my signature in presence of two witnesses.
